ellipsoid

ellipsoid

1.A three-dimensional, closed geometric shape, all planar sections
of which are ellipses or circles. An ellipsoid has three independent axes, and
is usually specified by the lengths a,b,c of the three semi-axes. If an
ellipsoid is made by rotating an ellipse about one of its axes, then two axes
of the ellipsoid are the same, and it is called an ellipsoid of revolution, or
spheroid. If the lengths of all three of its axes are the same, it is a sphere.

2.When used to represent the earth, an oblate ellipsoid of
revolution, made by rotating an ellipse about its minor axis.

Mining Engineering

Mining engineering is an engineering discipline that involves practice, theory, science, technology, and the application of extracting and processing minerals from a naturally occurring environment. Mining engineering also includes processing minerals for additional value.

Environmental Engineering

Environmental engineers are the technical professionals who identify and design solutions for environmental problems. Environmental engineers provide safe drinking water, treat and properly dispose of wastes, maintain air quality, control water pollution, and remediate sites contaminated due to spills or improper disposal of hazardous substances. They monitor the quality of the air, water, and land. And, they develop new and improved means to protect the environment.
